Application of 13C mineral carbon for assessment of the primary production of organic matter in aquatic environments

The possibility of measuring the rates of light and dark CO 2 assimilation using 13 C carbonate was demonstrated on Lake Kichier (Marii El). The application of methods utilizing the stable 13 C and the radioactive 14 C isotopes resulted in comparable values of the rates of light and dark CO 2 fixati...

Description
Summary:The possibility of measuring the rates of light and dark CO 2 assimilation using 13 C carbonate was demonstrated on Lake Kichier (Marii El). The application of methods utilizing the stable 13 C and the radioactive 14 C isotopes resulted in comparable values of the rates of light and dark CO 2 fixation. Due to its absolute environmental safety, the method with 13 C mineral carbon can be recommended as an alternative to radioisotope methods for qualitative measurements of CO 2 fixation rates in aquatic ecosystems.
